Shooting RAW+L (5DM2): JPEG White Balance viewing wrong.

In Capture One v.7 , and v.6 as well (Mac):
when shooting tethered with a Canon EOS 5D Mark II, file format set as RAW+L (Large) JPEG in camera settings and White Balance mode in C1 on "Custom", happens that JPEG file always get stuck with a wrong White Balance profil when ready.
Roughly, Kelvin value gets a +1000ºK and Tint one, a +60, which give it a very pinkish look.
But JPEG file itself is OK, color balance is fine as the one for the RAW file.
Just seems that C1 add a wrong WB profil on it only at the end of both files uploading.

When White Balance mode is set as "Shot" or "Auto", both RAW and JPEG files show correct White Balance profil (though on the JPEG file an extra average +300ºK will always be added...).

Something wrong in my capture settings?
Thanks' in advance for your advices and suggestions.
Philippe.

  Maybe something in your "Next Capture Adjustments"?

  Thank you Mogens for this suggestion but whatever the settings for Next Capture Adjustments, which i forgot to specify, like "Defaults", "Defaults with Styles", "Copy from Last", etc. the pinkish look on the JPEG is constant (with White Balance mode on "Custom").
  No idea from where it comes from...

  Philippe, this means that White Balance in C1 for the image being viewed has been altered, presumably by you. I think you must set it to something else, either "Shot" or one of the other canned settings. You seem determined that you should use "Custom" . May I ask why?
  
  Cheers,

  Do you get the same problem on your side when shooting RAW+L (if you own a 5DM2, or similar) ?

  You cannot trust the WB value of the jpeg as absolute, only for raw-files. For jpeg the response can be very different.
  
  The difference you see could be due to heavy in-camera adjustments, which CO cannot use or apply to the raw-file as they are Canon-proprietary.

  I made some testshots, each capture as raw-jpeg, with my camera (not a Canon), into C1, and into Lightroom.
  
  The C1 raw and jpeg look very different when viewed in C1. Not so outside of C1.
  
  The Lightroom raw and jpeg look the same whether viewed inside or outside of Lightroom.
  
  Edit:
  
  I found out that C1 is applying some adjustments to the jpeg file upon capture. I selected the raw file as well as the jpeg and reset all adjustments. That made then look virtually identical.
  
  The thing then would seem: How to avoid that C1 applies any adjustments to jpeg files upon capture?
  
  Edit:
  
  The reset of the jpeg changes the "Base Characteristics" ICC profile from a camera specific to "Jpeg File Neutral" How do users control that behaviour when tethering?
  
  Edit:
  
  - In "Base Characteristics" right-hand triangle, select "Reset Defaults for Jpeg File"
  - For "Next Capture Adjustments" ICC Profile, choose "Default"
  
  Cheers,
  Mogens

  (sorry for this late reply)
  Thanks' a lot Mogens for your time and tests done to find a fix.
  Following your suggestions, i tried on my side and could get an almost "OK-good-looking" JPEG file, along with its brother, the no-problem RAW file.
  But still some strange color cast, always redish/pinkish, is applied to it...
  Never mind, we got used to it and knowing the file itself is not corrupted, we don't bother anymore in the studios.
  And every cloud has a silver lining, it's much easier to see at a glance which file is a RAW and which one is an Halloween JPEG ! (no need to applied a global filter to show up only one format type)
  Thank you again.
